Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are “black boxes.” The initial response in the literature was a demand for “explainable AI.” However, recently, several authors have suggested that making AI more explainable or “interpretable” is likely to be at the cost of the accuracy of these systems and that prioritizing interpretability in medical AI may constitute a “lethal prejudice.” In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realized. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems, may itself constitute a form of lethal prejudice that may diminish the benefits of AI to—and perhaps even harm—patients.

What is it to be scientific? Is there such a thing as scientific method? And if so, how might such methods be justified? Robert Nola and Howard Sankey seek to provide answers to these fundamental questions in their exploration of the major recent theories of scientific method. Although for many scientists their understanding of method is something they just pick up in the course of being trained, Nola and Sankey argue that it is possible to be explicit about (...) what this tacit understanding of method is, rather than leave it as some unfathomable mystery. They robustly defend the idea that there is such a thing as scientific method and show how this might be legitimated. This book begins with the question of what methodology might mean and explores the notions of values, rules and principles, before investigating how methodologists have sought to show that our scientific methods are rational. Part 2 of this book sets out some principles of inductive method and examines its alternatives including abduction, IBE, and hypothetico-deductivism. Part 3 introduces probabilistic modes of reasoning, particularly Bayesianism in its various guises, and shows how it is able to give an account of many of the values and rules of method. Part 4 considers the ideas of philosophers who have proposed distinctive theories of method such as Popper, Lakatos, Kuhn and Feyerabend and Part 5 continues this theme by considering philosophers who have proposed naturalised theories of method such as Quine, Laudan and Rescher. This book offers readers a comprehensive introduction to the idea of scientific method and a wide-ranging discussion of how historians of science, philosophers of science and scientists have grappled with the question over the last fifty years.

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

Some rules seem more important than others. The moral rule to keep promises seems more important than the aesthetic rule not to wear brown with black or the pool rule not to scratch on the eight ball. A worrying number of metaethicists are increasingly tempted to explain this difference by appealing to something they call “authoritative normativity” – it’s because moral rules are “authoritatively normatively” that they are especially important. The authors of this chapter argue for three claims concerning “authoritative (...) normativity”: (1) that motivation for it originates in a parochial conception of “normative flavours”; (2) that arguments against alternative ways of explaining e.g., morality’s importance are overblown; and (3) that there are strong reasons against theorizing in terms of “authoritative normativity”. The overarching aim is not to show that “authoritative normativity” is incoherent or entirely unmotivated. Rather, it is to discuss some of “authoritative normativity’s” deeper commitments to correct the impression that is it largely benign or that it is entailed by familiar and popular “metanormative” positions. Authoritative normativity, it seems to us, is a solution in search of a problem. (shrink)

Several issues are raised concerning the notion that a single strategy explains Fitts' law and the linear speed/accuracy trade-off. Two additional concerns are discussed: (1) distance is programmed, (2) the fact that movements produced without the aid of vision obey Fitts' law does not mean that sighted movements must be explained without regard to vision.

While it is tempting to suppose that an act has moral worth just when and because it is motivated by sufficient moral reasons, philosophers have, largely, come to doubt this analysis. Doubt is rooted in two claims. The first is that some facts can motivate a given act in multiple ways, not all of which are consistent with moral worth. The second is the orthodox view that normative reasons are facts. I defend the tempting analysis by proposing and defending a (...) heterodox account of both normative and motivating reasons that is inspired by Donald Davidson’s primary reasons. We should adopt the heterodox view, I argue, because it addresses an overlooked but fatal defect in the orthodox conception of reasons, of which challenges to the tempting analysis are a special case.

I defend the widely-held view that morally worthy action need not be motivated by a desire to promote rightness as such. Some have recently come to reject this view, arguing that desires for rightness as such are necessary for avoiding a certain kind of luck thought incompatible with morally worthy action. I show that those who defend desires for rightness as such on the basis of this argument misunderstand the relationship between moral worth and the kind of luck that their (...) argument employs. Consequently, the argument provides no reason to doubt the popular view that a desire for rightness as such is no part of virtue. I conclude by suggesting that a family of worries about merely accidentally right action presuppose one side of the recent debate about objectivism and perspectivism about moral rightness. (shrink)

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

Book reviewed in this article: The Healer's Power. By Howard Brody.

Inflicting harm is generally preferable to inflicting death. If you must choose between the two, you should generally choose to harm. But prenatal harm seems different. If a mother must choose between harming her fetus or aborting it, she may choose either, at least in many cases. So it seems that prenatal harm is particularly objectionable, sometimes on a par with death. This paper offers an explanation of why prenatal harm seems particularly objectionable by drawing an analogy to the all-or-nothing (...) problem. It then argues that this analogy offers independent support for the ‘voluntarist’ view that at least some parental role obligations are grounded in the choice to be a parent. (shrink)

Some have attempted to explain why it appears that action based on deferential moral belief lacks moral worth by appealing to claims about an attitude that is difficult to acquire through testimony, which theorists have called “moral understanding”. I argue that this state is at least partly non-cognitive. I begin by employing case-driven judgments to undermine the assumption that I argue is responsible for the strangeness of deferential moral belief: the assumption that if an agent knows that some fact gives (...) them a moral reason to act in some way, then they’re in a position to act that way for the moral reason given by that fact. I then argue that cases from non-moral epistemology concerning properly-based belief give us independent reason to reject this assumption and conclude by sketching a Davidson-inspired account of normative reasons that explains why acting for moral reasons requires the right non-cognitive state, which is worth calling a kind of moral understanding.

Philosophers have recently come to focus on explaining the phenomenon of ​bad beliefs,​ beliefs that are apparently true and well-evidenced but nevertheless objectionable. Despite this recent focus, a consensus is already forming around a particular explanation of these beliefs’ badness called ​moral encroachment​, according to which, roughly, the moral stakes engendered by bad beliefs make them particularly difficult to justify. This paper advances an alternative account not just of bad beliefs but of bad attitudes more generally according to which bad (...) beliefs’ badness originates not in a failure of sufficient evidence but in a failure to respond adequately to reasons. I motivate this alternative account through an analogy to recent discussions of moral worth centered on the well-known grocer case from Kant’s ​Groundwork​, and by showing that this analogy permits the proposed account to generalize to bad attitudes beyond belief. The paper concludes by contrasting the implications of moral encroachment and of the proposed account for bad attitudes’ blameworthiness. (shrink)

I propose and defend a novel view called “de se consequentialism,” which is noteworthy for two reasons. First, it demonstrates—contra Doug Portmore, Mark Schroeder, Campbell Brown, and Michael Smith, among others—that agent-neutral consequentialism is consistent with agent-centered constraints. Second, it clarifies the nature of agent-centered constraints, thereby meriting attention from even dedicated nonconsequentialists. Scrutiny reveals that moral theories in general, whether consequentialist or not, incorporate constraints by assessing states in a first-personal guise. Consequently, de se consequentialism enacts constraints through the (...) very same feature that nonconsequentialist theories do. (shrink)

Vision consists of four essays: “Seeing distance,” “Size,” “Perceptual inference,” and “A Gibsonian alternative?” The continuous thread is the Berkeleian treatment of the perception of spatial properties, particularly in connection with what is and is not “immediately perceived.” The first two essays are closely connected with specific Berkeleian arguments and modern responses to them. The second two essays deal more generally with modern discussions by psychologists of whether visual perception is “direct” or “indirect.” The claims on the cover that the (...) book is “unique in its blend of philosophical and historical perspectives on contemporary issues in vision studies” and that it is “clearly written” and suitable “for an interdisciplinary readership in philosophy of mind, philosophy of science, cognitive psychology and history of science” are all entirely justified.

The wrong kind of reason (WKR) problem is a problem for attempts to analyze normative properties using only facts about the balance of normative reasons, a style of analysis on which the ‘Reasons First’ programme depends. I argue that this problem cannot be solved if the orthodox view of reasons is true --- that is, if each normative reason is numerically identical with some fact, proposition, or state-of-affairs. That’s because solving the WKR problem requires completely distinguishing between the right- and (...) wrong-kind reasons for an attitude. I argue that some facts give both right- and wrong-kind reasons for an attitude. Consequently, no such distinction between the two types of reasons is complete if reasons are facts or the like. I conclude by suggesting that reasons and facts are related by constitution, not identity. (shrink)

Critical Reflections on Teacher Education argues that educational philosophy can improve the quality of teacher education programs in Canada, the United States, and the United Kingdom. The book documents the ways in which the market model of education propagated by governments and outside agencies hastens the decline of philosophy of education and turns teachers into technicians in hierarchical school systems. A grounding in educational philosophy, however, enables future teachers to make informed and qualified judgements defining their professional lives. In a (...) clear and accessible style, Howard Woodhouse uses a combination of reasoned argument and narrative to show that educational philosophy, together with Indigenous knowledge systems, forms the basis of a climate change education capable of educating students about the central issue of our time.

‘Treatment’ from which the patient cannot benefit is sometimes administered to a patient so that the comfort of the patient's family or caregivers may be increased. Is this permissible? To answer that question we will explore the interests of the permanently unconscious patient and the potential for such a patient's interests to conflict with those of her family and healthcare providers. We will conclude that in the likely absence of a specific advance directive from the patient providing for such circumstances, (...) treatment for the benefit of the family may be given so long as it is not abusive. However, treatment solely for the comfort of caregivers may not be given without consent of the patient's surrogate decisionmakers. (shrink)

There’s a long but relatively neglected tradition of attempting to explain why many researchers working on the nature of phenomenal consciousness think that it’s hard to explain.1 David Chalmers argues that this “meta-problem of consciousness” merits more attention than it has received. He also argues against several existing explanations of why we find consciousness hard to explain. Like Chalmers, we agree that the meta-problem is worthy of more attention. Contra Chalmers, however, we argue that there’s an existing explanation that is (...) more promising than his objections suggest. We argue that researchers find phenomenal consciousness hard to explain because phenomenal concepts are complex demonstratives that encode the impossibility of explaining consciousness as one of their application conditions.

ABSTRACT Normativity seems characteristically, perhaps essentially, explained by claims about the competition between normative reasons. John Broome’s ‘quick objection’ aims to show that rationality cannot be explained by claims about normative reasons and, thus, that it is not normative. Broome’s objection turns on the idea that rationality is mind-dependent in a way that facts about reasons are not. However, this objection is shaped by a popular, powerful, and restrictive assumption about the substance of normative reasons called factualism, which holds that (...) the substances that are reasons are facts, either in the sense of true propositions or of the truth-makers of such propositions. I suggest that support for factualism is weaker than its popularity suggests. In particular, I suggest that arguments for factualism from (1) the nature of normative explanation, (2) expressions attributing reasons, (3) the relationship between normativity and actuality, and (4) common sense are weaker than they appear. Rejecting factualism allows us to tie some class of reasons—subjective reasons, we might call them—more closely to the mind and to thereby ground the normativity of rationality. Thus, Broome’s ‘quick objection’ is too quick for it must account for the possibility of non-factualist reasons. (shrink)

It is likely that sex robots will exist in the near future, making the effect they might have on human relationships a pressing concern. In this future world, we can imagine sex robots shaping our personal and social relationships through their unique access to, and potential for influencing, our most intimate of behaviours. We investigate whether they might be employed to influence social behaviours in a positive way. The paper begins with an account of the state of the art, acknowledges (...) powerful feminist criticisms that have been made of sex robots, and evaluates suggestions that it might be possible to design sex robots which do not raise these concerns and which might even work to influence social behaviours in a positive way. It then outlines a number of ways that sex robots might be used to educate, “nudge”, and influence people in positive ways. It defends the idea that it would be ethical to use sex robots to promote socially positive behaviours — behaviours that benefit others and improve social cohesion, such as fostering respect and empathy for persons — but not to promote commercial products for parochial interests. We argue that the former project could advance individual and social welfare, while preserving personal autonomy — a minimum requirement of which is the ability to make informed decisions — whereas the latter depends on a lack of transparency and democratic control for its success, targets the vulnerability of the user to achieve its ends, and reinforces the problematic symbolism of negatively gendered sexuality. If sex robot design and application meet public requirements of transparency — enabling informed consent and reflective decision making — and democratic oversight — promoting accountability and the sharing of power with the public — it is conceivable that sex robots might assist, rather than harm society.

Males traditionally predominate at upper achievement levels. One general view holds that this is due only to various social factors such as the and lack of female role models. Another view holds that it occurs partly because of innate ability differences, with more males being at upper ability levels. In the last few decades, women have become more achievement focused and competitive and have gained many more opportunities to achieve. The present study examined one intellectual domain, international chess, to quantify (...) its gender differences in achievement and to see if these have been diminishing with the societal changes. Chess is a good test domain because it is a meritocracy, it has objective performance measures, and longitudinal data of a whole population are available. Performance ratings overall and in the top 10, 50 and 100 players of each sex show large gender differences and little convergence over the past three decades, although a few females have become high achievers. The distribution of performance ratings on the January 2004 list shows a higher male mean and evidence for more male variation, just as with traits such as height. Career patterns of players first on the list between 1985 and 1989 show that top males and females entered the list at about the same age but females tend to play fewer games and have shorter careers. In this domain at least, the male predominance is large and has remained roughly constant despite societal changes. (shrink)

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture changes (...) during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.
